flat spot in 3rd gear/entering highway
I have a 98 F-150 with a 4.6 K/n fipk dual exh. and a b/m electronic shift imp. Well,the
problem I'm having is not major but is a little disappointing. When I am on a freeway
entrance ramp,the engine performance seems to
drop off a little. This happens about the middle of 3rd gear and goes away after a couple of seconds,it then begins pulling strongly again. Any suggestions?

watch your tach. My truck seems to have a dull area from about 2200 to 2600 rpm. Then about 2700 rpm to 3900 rpm it climbs like crazy. This is called torque band and may be what you are experienceing.
